A New Paper Investigates The Physics Of Batman's Wingsuit

David Marshall and fellow students found that while Batman could glide great distances, he would suffer grievous injury with no way to slow his descent:

Batman's descent is rapid, even for this high estimate for the lift coecient. Looking at the case for gliding from a fairly tall building of height 150m, Batman can glide to a distance of about 350m, which is reasonable; the problem with the glide lies in his velocity as he reaches ground level. The velocity rises rapidly to a maximum of a little over 110km=hr before steadying to a constant speed of around 80km=hr. At these high speeds any impact would likely be fatal if not severely damaging (consider impact with a car travelling at these speeds).
